A `further object of the invention is to provide a railway signalmechanism of the above. type wherein the car ,or train is equipped witha'novel construction of trolley pole'arms adapted to beengaged withspaced wires disposed above the track siding foruclosing a vcircuit togive ay signal in the car or train and Vin the switchmans house when thetrain has been accidentally switched fromjaxmain line to sidingl Y YWith the above and other objects in view that will become apparent asthe nature of the invention is betterunderstood, the same consists inthe novel form, combination and arrangement of partshereinafter morefully described, shown in the accompanying drawings and claimed.
